Hi John:

Well, the usual issue when CMake cannot find libraries is the
"development" versions of the cairo, qt, and tk library packages have not been
installed.  Which should be an easy problem to fix....

Actually, I have never had a problem like that with -dev xwin so you
might be up against a packaging error of some kind.  To confirm or
eliminate that possibility, what happens for the version you build
yourself (as above, but with all relevant library development packages
installed)?

If the version you build yourself also has the problem, then I suggest
you try the -debug option which should give more details on what
exactly is going wrong for -dev xwin.

Good luck, and let us know how it goes.
